Coastal Environment Generation with HoloOcean

Testing autonomy and perception for unmanned underwater and surface vessels requires realistic coastal environments, which have traditionally demanded tedious manual creation in 3D engines. This paper introduces an Unreal Engine 5 level generation pipeline tailored for the HoloOcean simulator. Driven by a single user-provided overhead image, the workflow automatically generates terrain height maps and handles asset selection and placement, lowering the barrier to creating custom maritime digital twins.
